The incident took place in a residence just before the New Year, sometime between December 29 and 30.
The suspect, who is reported to have had a relationship with the woman, was arrested in his absence on Tuesday. He was arrested the following day, has been in custody since then and was remanded in custody in Örebro district court on Saturday.
According to the prosecutor, he denies any crime. Reasonably suspicious is the lower degree of suspicion.
